Alejandro Abdelnur commented on YARN-803:
-----------------------------------------

Zhijie,

On adding the setConf() method to the scheduler API, it is up to the scheduler impl to use or not the Yarn configuration. If a scheduler impl decides to do so, by implementing Configurable it will get it.

I've initially thought about adding a validateConf() method to the scheduler API. I've decided to go the Configurable route for the reason above.

Because of that, I think we should do things as in the current patch.
